Abstract. Irregular pyramids organize a sequence of partitions of images in such a way that each partition is deduced from the preceding one by union of some of its regions. In this paper, we show how a single pyramid can be used to encode redundant subparts of different partitions. We obtain a pyramid that accounts for the redundancy of the partitions. This structure, naturally called the redundancy pyramid, can be used for many purposes. We also demonstrate and discuss some applications for studying image sequences.
